Thanks for the kind words. The garage is a labor of love. I put down the Vinyl Composite Tile (VCT) floor almost seven years ago then a couple years later I installed mirrored wardrobe closet door across the back to conceal the shelves. I bought a high speed polisher off of Craigslist and burnish it a couple times a month. It is far from maintenance free but I enjoy how it looks and the upkeep. It is like waxing the cars. Fun stuff.
I believe one reason my wheel wells cleaned up so well is the car only has 24,000 miles on it and it has never been driven in the rain. I used Lexol Vinylex to clean the wheel well liners. I also use it on the tires and all rubber, plastic and vinyl parts on the cars. Great stuff. I use so much of it I buy it by the gallon. Love cleaning!
I am fighting the urge to get under the car and wipe down all of undercarriage. I bet it would clean up real nice.
